Convert Liters per 100 km to Kilometers per Liter

The L/100km-to-km/L conversion appears often when working with fuel economy data across different unit systems. Fuel economy is expressed differently worldwide: the US uses miles per gallon, Europe often uses liters per 100 kilometers, and efficiency can also be stated as kilometers per liter.

Formula: Divide 100 by the liters-per-100-km value. In equation form: km/L = 100 ÷ L/100km.

One liters per 100 km equals approximately 100 km/L. This means you can multiply any L/100km value by 100 to get the equivalent in km/L.

For instance, converting 25 L/100km gives 4 km/L. Try different values using the quick-value chips or type directly into the input field.

Common mistake: Higher mpg means better efficiency, but lower L/100km also means better efficiency — these scales run in opposite directions, so do not compare the numbers directly without converting.
